In Chapter 7, of Catcher in the Rye, Holden goes into Ackley's room. Holden has just had a fight with Stradlater over the essay that Holden wrote for him. Stradlater tore up the essay; Holden was very upset about this given the essay was about his deceased brother's baseball mitt. Stradlater began hitting Holden and eventually pinned him to the ground only promising to let Holden up if he kept his mouth shut (Holden had repeatedly called him a moron). After the fight, Holden decides to go into Ackley's room because he had certainly heard the fight and was awake. Holden also wanted to see what Ackley was doing given that Ackley had very bad "personal habits".
